The Nostr Apps directory shows how broad the ecosystem already is: microblogging, photos, streaming, blogging, group chat, community tools, signers, discovery, media, maps, marketplaces and developer utilities.
Why this catalog exists
A complete Nostr archive needs more than abstract protocol pages. It needs product evidence. This catalog turns the public Nostr Apps directory into a Crays-readable structure without pretending that every entry is mature or strategically important.
The goal is coverage first, then judgment. Every app gets a place. The best candidates for Crays can then be tested and expanded later.
- Captured apps. 72
- Captured categories. 22
- Editorial rule. Do not copy the app directory; create independent context and link to source pages.
